Hello, The problem that i have on my mx4 pro are:
1) Using a generic wall charger or USB connection from computer
---- Not charging at all, took more than 1 hour to increase 1 or 2 % of battery.
2) Using original charger
---- I'm able to charge the phone, but most of the time my phone goes crazy (disconnecting charging and connecting charging several times) until i disconnect the phone.
Actual firmware: 22.214.171.124
